• Javascript : You can compile a haXe program to a single .js file. You can access the typed browser DOM APIs with autocompletion support, and all the dependencies are resolved at compilation time.
• Flash : You can compile a haXe program to a .swf file. haXe can compile for Flash Players 6 to 9, with either “old” Flash<8 API or newest AS3/Flash9 API. haXe offers very good performance and language features to develop Flash content.

• a standardized language with many good features
• a standard library (including Date, Xml, Math…) that works the same on all platforms
• platform-specific libraries : the full APIs for a given platform are accessible from haXe
